I fabricated and assembled 5 custom BLE boards with BCM20732S. 1 of it does not even program, but 4 of them can be detected and programmed with the ROM Heart Rate Monitor sample app successfully.
However, only 1 of them works fine. The other 3 will only advertise during startup and then stops advertising. I couldn't figure out why 1 of them works perfectly fine, while the other 3 stops advertising after startup.
